Krause posted the video on YouTube on Aug. 22 and it's quickly going viral with TV news stations picking up the footage.

The humpback is so close to the boat that you have to wonder whether the situation was safe.

In the comments on YouTube, Steve Heise posted, "My wife was on this boat. A retired whale watching captain told my wife later when he saw this video that the boat could have been badly damaged and people hurt. Their boat was only as long as the whale and could have sunk it. Glad she survived!"
